Oil-Free Scroll Compressor

Oil-free scroll compressors offer OEMs a quiet and smooth-operating alternative to traditional reciprocating and vane compressors.

Air Squared uses a non-contacting scroll configuration that requires zero lubrication – no contamination, no filter, no pump, just clean air without the impurities of oil.

Scroll technology is considerably quieter and smoother than traditional reciprocating, diaphragm, and vane technology.

The scroll geometry delivers continuous flow and eliminates the need for valves, resulting in significantly less port pulsation and associated valve noise. The unique orbital motion is dynamically balanced, minimizing vibration and reducing rubbing velocity far below piston rings or vanes.

Air Squared uses a simplistic scroll design approach, with few moving parts and lightweight aluminum construction. Variable speed operation allows space-constrained applications to maximize performance by running at higher speed.

Scroll technology has minimal re-expansion losses – a problem found in reciprocating machines with every piston stroke – greatly improving volumetric efficiency. Throttling losses are also nonexistent with the valveless design.

Scroll technology is durable and robust, with 70% fewer moving parts than reciprocating technology. With only two primary components, the scroll design is highly reliable and easily serviceable.
